The main problem is caused by the mismatch between
/cupsBitsPerColor 8 and the default value of /GrayValues , which is not
adjusted when /cupsBitsPerColor is set but checked later when the page device
is restored. Modifying the sample file as
s|/cupsBitsPerColor 8|/cupsBitsPerColor 8/GrayValues 256|
makes the file run to completion.

Non-standard and duplicate page device parameters are confusing.
Several approaches are possible and we need to discuss how to proceed.
